==Former Constituents / History of the Index==

Some time ago I have started working on a proposal to improve the former members section and present it as a history of the members of the index but due to time constraints I never finished this project. The table below is where I had got to incorporating changes from 1986 to October 1995.

Not sure that I am going to have time to take this forward again but if I do find myself with free time I might pick this back up. Posting here to get a view on what people think about making such a change to the article (this would replace the existing former constituents section) as, if the general consensus is that my proposal is a bad idea, then I certainly don't want to waste time on it. Also posting here in case anyone else has a similar idea and its something they want to take forward. 

Blanks on the deleted (as of now) represent entities that either were deleted post October 1995 and therefore are ones I've not yet updated or are current constituents (which ultimately I'd probably look to highlight in some way if I ever get to that stage). Anyone who was not a member by October 1995 is not yet in the table as I hadn't got that far in updating it. Was updating in order by reference to the FTSE Russel history list. 

Any and all thoughts welcome.[[User:Tracland|Tracland]] ([[User talk:Tracland|talk]]) 07:51, 7 January 2023 (UTC)

== Creation of new category ==

If we look at [[:Category:Companies by stock market index]], most of the world's major indices are listed, except for the FTSE. Can somebody add this? [[Special:Contributions/92.71.60.62|92.71.60.62]] ([[User talk:92.71.60.62|talk]]) 09:26, 6 November 2023 (UTC)

:Done. [[User:Dormskirk|Dormskirk]] ([[User talk:Dormskirk|talk]]) 10:14, 6 November 2023 (UTC)
::Thanks for doing that, but what I meant was, creation of a new category (ie ''Companies in the FTSE‎ 100''). I can then add that category to the pages for AstraZeneca, Vodafone, etc...  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/92.71.60.62|92.71.60.62]] ([[User talk:92.71.60.62#top|talk]]) 12:54, 6 November 2023 (UTC)</small> <!--Autosigned by SineBot-->
:::We would need consensus to do that, especially as the category would need to be maintained: views from other editors welcome. [[User:Dormskirk|Dormskirk]] ([[User talk:Dormskirk|talk]]) 13:38, 6 November 2023 (UTC)
::::Well, there are already 20 such categories (CAC 40‎, Dow Jones Industrial Average‎, Nasdaq-100‎, SSE 50), I think this index has simply been overlooked. I don't mind doing the work of adding it to all the pages, it's just getting the thing created in the first place.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/92.71.60.62|92.71.60.62]] ([[User talk:92.71.60.62#top|talk]]) 14:58, 6 November 2023 (UTC)</small> <!--Autosigned by SineBot-->
:::::OK. I have now set up the category: (Category:Companies in the FTSE 100 Index). I have already added two companies to the category to get you started. Please go ahead and populate it with the rest. Thanks. [[User:Dormskirk|Dormskirk]] ([[User talk:Dormskirk|talk]]) 15:16, 6 November 2023 (UTC)
::::::That's great, thanks!

::::::::::No, it's perfect the way it is. We can use the existing geographic and industry categories to list intersections with FTSE 100.

:::::::::::Great. [[User:Dormskirk|Dormskirk]] ([[User talk:Dormskirk|talk]]) 09:59, 8 November 2023 (UTC)
::::::::::::While we're on the subject, there are a couple of other major indices without a category, namely DAX, Nikkei 225, S&P/ASX 200, NIFTY 50, OMX Stockholm 30, KOSPI. Any chance you could create those too?  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/92.71.60.61|92.71.60.61]] ([[User talk:92.71.60.61#top|talk]]) 08:30, 9 November 2023 (UTC)</small> <!--Autosigned by SineBot-->
:I am less familiar with those indicies and suggest you approach someone who is more knowledgeable on them. Alternatively, if you set up your own wikipedia account, and once you have completed 500 edits, you should be able to set them up yourself.

:::I am not sure that a FTSE 250 Index category is needed. It will require a lot of maintenance, as changes to the index happen frequently. [[User:Dormskirk|Dormskirk]] ([[User talk:Dormskirk|talk]]) 08:51, 10 November 2023 (UTC)
::::But if you still want to do the FTSE 250 Index, I am happy to set up the category. You will need to add the category to all the articles again. Just let me know. [[User:Dormskirk|Dormskirk]] ([[User talk:Dormskirk|talk]]) 08:04, 14 November 2023 (UTC)
:::::I still think it's a good idea. It's not a contentious category, and you only have perhaps a dozen  replacements per year. I'd be happy to populate.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/92.71.60.61|92.71.60.61]] ([[User talk:92.71.60.61#top|talk]]) 09:35, 14 November 2023 (UTC)</small> <!--Autosigned by SineBot-->
:::::::Now set up. Please go ahead and populate. Thanks. [[User:Dormskirk|Dormskirk]] ([[User talk:Dormskirk|talk]]) 09:47, 14 November 2023 (UTC)

:The IP has spammed dozens of messages {{diff|User talk:Redrose64|prev|1185527576|like this}} to user talk pages, and some of them have received replies ([[User talk:Colonies Chris/Archive/2023/Dec#Creation of new category]], [[User talk:DocWatson42#Creation of new category]], [[User talk:Howard the Duck#PSE and other categories]], [[User talk:ShakespeareFan00#Creation of new category]]). This FTSE 100 thread appears to be the first such request; really, it should all have been done at some central discussion page like [[Wikipedia talk:WikiProject Finance & Investment]] - in this way, discussion could have been conducted together and duplication of effort could have been avoided. --[[User:Redrose64|<span style="color:#a80000; background:#ffeeee; text-decoration:inherit">Red</span>rose64]] &#x1f339; ([[User talk:Redrose64|talk]]) 11:16, 17 November 2023 (UTC)
::Way to go with the overreaction! Reverting/deleting about 30 topics? You call it "spam", others would call it "reaching out to others in a position to help". The original discussion ''was'' centralized at [[Category talk:Companies by stock market index]], but there was no response. Hence reaching out to specialists in each area. if you took the time to notice, each message was individually tailored to each user's recent edits. Maybe in the future you could stop being such a fucking dick. <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/92.71.60.61|92.71.60.61]] ([[User talk:92.71.60.61#top|talk]]) 11:47, 17 November 2023 (UTC)</small>

:::Also, 92.71.60.61, in what way am I a specialist in that area, and how was {{diff|User talk:Redrose64|prev|1185527576|this edit}} individually tailored to my recent edits?
:::When editing [[Category talk:Companies by stock market index]] you will have seen [[Template:Editnotices/Namespace/Category talk|this message]] - notice the phrase "Talk pages in this namespace are generally not watched by many users" - in fact, the page has just four watchers, so it's no surprise that there was no response. --[[User:Redrose64|<span style="color:#a80000; background:#ffeeee; text-decoration:inherit">Red</span>rose64]] &#x1f339; ([[User talk:Redrose64|talk]]) 15:03, 17 November 2023 (UTC)
::::Well, you're one of the last 10 people to edit [[:Template:MOEX Russia Index]]. Anyway, I've started this discussion at the Project page, but really, the effort you've put into going backwards and forwards, categories for all the major indices in the world could already have been created by now.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/92.71.60.61|92.71.60.61]] ([[User talk:92.71.60.61#top|talk]]) 15:47, 17 November 2023 (UTC)</small> <!--Autosigned by SineBot-->
:::::{{diff|Template:MOEX Russia Index|prev|819021935|This bugfix edit}} from more than five years ago counts for nothing; I was fixing up an incomplete template move made a few weeks earlier by another user, who I also see that you spammed today even though they have not edited anything at all for more than seven months. --[[User:Redrose64|<span style="color:#a80000; background:#ffeeee; text-decoration:inherit">Red</span>rose64]] &#x1f339; ([[User talk:Redrose64|talk]]) 16:29, 17 November 2023 (UTC)
::::::So, just to be clear - IP users can't create categories, so they ask assistance on the talk page of the parent category. They're directed to ask other users. Most of the discussions get deleted. Other users tell them to link the categories anyway, resulting in redlinks. Other editors revert all the redlinks. Other editors suggest they ask on the Wikiproject. Editors in the project suggest they ask on the talk page of the parent category! WTF guys.
:::::::So, when IPs have been able to create categories in the past, I seem to remember it taking about 10 seconds. What are we here, 18 days in to the conversation with no clear way forward?
